SRAM helped pioneer the 1x drivetrain, and the SRAM Force® 1 crankset evolves the innovation. It's lighter, stronger and simpler non-aero chainrings can now be installed with a single tool. For cross, TT, tri, and crits, this is the king of 1x. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

SRAM's new DUB technology is all about the relationship between the bottom bracket spindle and bearing. It's where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler - better integrating the relationship between chainring, crank, spindle, and bottom bracket.

SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.

Road bikes are faster and more capable than ever before, and riders are expanding what's possible with drop bar bikes. X-Range is gearing for today's road riding. SRAM completely reimagined road gearing for wider range, more useful, and smoother gear progression. With X-Range, you're always in the right gear. To enable X-Range gearing technology, SRAM needed to develop a narrower chain. The unique link shape of Flattop technology not only allowed for a wider gear range but also results in quieter drivetrain operation and increased chain strength and durability. Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrow overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.
